Patented Sept. 12, 1944 UNITED STATES PATENT; I DEF-ICE 2,358,141.... a7 A i F KNA K ,1 v Arnett Bye'rs'. East Chicagmlnd. ApplicationSeptember s, 1943, Serial No. 592.65g 4 Claims. (01. 214- -100)- Myinvention relates to improvements in furnace jacks and it moreespecially includes the features pointed out in the annexed claims.

The purpose of my invention is to provide selfcontained means that willfacilitate the assembling of residence furnaces; that instead of usingthree or four men to assemble the top sections of a furnace I am able todo the same job in a much shorter time by a single man in cooperationwith my lifting means. The device is equally operable under any othercircumstances where heavy castings need to be lifted to a higher plane.These top sections of furnaces Weigh several hundred pounds and besidesbeing very heavy they are exceedingly awkward to handle.

With these and other related ends in view I illustrate on theaccompanying drawings such instances of adaptation as will show thebroad features of the invention without limiting myself to the specificdetails shown thereon and described herein.

Fig. 1 is a side elevation of my device in position alongside of aresidence furnace.

Fig. 2 is a front elevation of the device shown in Fig. 1, in directprojection.

Fig. 3 is a side elevation of the upper end of the device.

Fig. 4 is a detached elevation of the hook upper end of the inclinedplane.

Fig. 5 is a plan view of the lower endof the device.

Fig. 6 is a side elevation of the lower end of the let 3. In order toput the top sections into posi- V the hook ends 22 of thejack rods '9.There are two of these'rods, one on each'side-of the 'plank center.

A slightly curved sliding member l0 straddles the planks 1 and it isheld against sidewise movement by the pins l2 which engage the sideedges of the planks. The curved portion ID has side extensions I6 whichare provided with openings 2| for the reception of the hook ends I! ofthe lack swivel l9. There is one of these swivels for each one of thejack rods 9. The hook extension ll enter the openings 2|. The part I0has a bracket II with a brace I5 welded onto it. The lower leg of thebracket ll rests on the boards I and it serves to hold the part II] inposition on the planks to form a support for the sections 2 as they arerolled into position, one by one and then raised.

There is a jack l3 for each rod 9 and each jack has one ofthe ferrulesor swivels I9 which engage the extensions 16. They are free to turn on aprojection of the sheet metal casing'of the jacks I3. As shown the jacksl3 are each provided with an operating handle [4. The jack rods 9 passentirely through the jacks. The structure of these jacks isconventional. They are provided with a pair of loose floating dogs 20that alternately cooperate with a spring 24 and a washer 23 throughwhich the jack rods 9 pass. The movement of the lever I4 with eachdownward push engages the washer and it in turn grips the rod 9 movingthe section a short distance up. On the reverse movement of the handlethe loose dogs prevent the load slipping back on the planks. The nextmovement of the lever will again advance the support I0 upward, carryingwith it one of the sections 2. After a section 2 has been placed on topof the furnace the hooks 5 are put onto the top of the next section, asshown by dotted lines in Fig. 1, and the bottom end of the boards isshifted accordingly along the floor. When a section has been lifted intoplace a slight release of the dogs 20 will let the jacks and theconnected support l0 slide to the bottom ready to receive the nextsection.

Should it be desired the two handles [4 may be interconnected by anyconventional coupling bar (not shown) so that a single movement willoperate both jacks at the same time.

My device is quite simple and inexpensive in contrast to the use ofthreaded or notched rods. The wooden planks I may be substituted bymetal plates if desired.

What I claim is: Y

1. A portable inclined plane comprising a main member adapted to reachfrom an elevation to the ground, means at the elevated end to engage aprojection of the object being served, a movable member at the other endof the incline, means comprising parallel rods connecting the movablemember with the upper end of the incline, and means for sliding themovable member and a load up the incline by intermittent frictionalimpulses on the connect-ingfmeans:

2. A furnace jack which comprises a, weight carrying incline, means formoving a weighted object up the incline said means including a fric-.tional applied jack, a duplicate jack, a separate.

traveling rod for each jack, means for joining the rods at the bottomend of the incline said.

means being adapted to hold the object to be moved up the incline, meansfor'holding the'upper end of the incline against movement on the:

object that is being served and means for intermittently operating thejacks.

3. A portable incline which comprises, means at one end for resting itelevated on a. portion of a furnace, a pair of parallel rods, a movablemember at the other end of the incline operative on said rods adapted toengage an object to be placed on the furnace, and means acting on saidrods
